ARTHUR HARRISON, OF BARROIV-IN-FURNESS, COUNTY OF LANCASTER, ASSIGNOR TO IVILLIAAI FRANKLIN RICHIE, OF LONDON, ENGLAND.

APPARATUS FOR MOVING BODIES OF METAL INTO AND OUT OF FURNACES.

SPECIFICATION forming part of Letters Patent No. 395,135, dated December 25, 1888. Application filed October 23, 1888. Serial No. 288,835. (No model.) Patented in England July 15. 1886, No. 9,198.

To all whom it may concern.-

Be it known that I, ARTHUR HARRISON, a citizen of England, residing at Barrow-in- Furness, in the county of Lancaster, England, have invented a new and useful Apparatus for Moving. Heavy Pieces into and out of Furnaces, (for which I have obtained a patent in Great Britain, dated July 15, N86, No. 9,198,) of which the following is a specification.

My invention relates to apparatus wherein a hydraulicallyavorked peel receives on it a heavy piece of metal, raises the same, introduces it into a furnace, lowers it' down on supports therein, and is withdrawn, leaving the piece in the furnace; or, by inversion of the operations mentioned, it takes a piece out from the furnace. The apparatus is, moreover, arranged on a pivot, so that by sweeping it round it can be used for a number of furnaces surrounding the pivot.

Figure l of the accompanying drawings is a side view, and Fig. 2 is a plan, of apparatus according to my invention.

011 a stand, A, is pivoted by a boss, I), a girder, l3, havin at its other end a truck, so that it can sweep round the pivot A, the truck running on the floor. 011 the under side of the girder B are lixed two hydraulic cylinders, E, chains from which pass round a circular-h grooved part of the stand A, so that on s aining the chain on the one side by subjecting the plunger of the one cylinder E to pressure while the other is relieved from pressure the girder B can be swept round in either direction. On trunn ions on the girder l) is mounted another hydraulic cylinder, G, having water-passages through its trunnions, so that pressure can be made to act on either side of a piston in the cylinder, the rod of which projects through stuffing-boxes at both ends of the cylinder.

On the front end of the rod is fixed an arm, F, constituting a peel, which rests on rollers mounted in the truck C. i

The middle roller is on the plunger of a hydraulic cylinder, H, which when subjected to pressure raises the peel F, the cylinder G turning partly on its trunnion A forging or other piece, K, having been laid on the peel F, it is raised by the plunger of H, and then by pressure on the piston of G the peel, with its load, is advanced into a furnace. By relieving the pressure in II the peel F is allowed to descend, leaving the piece K resting on supports in the furnace, and then by reversing the pressure in G the peel is withdrawn.

For taking a piece out of the furnace the operation of the parts is inverted--that is to say, the peel F is advanced into the furnace under the supported piece K. The peel is then raised, lifting K off its supports, and the peel is then withdrawn, carrying the piece K upon it.

Having thus described the nature of my invention and the best means I know for cari: ing the same into practical effect, I claim as my invention Apparatus for moving heavy pieces into and out of furnaces, consisting of a girder pivoted at one end and supported on a truck at the other end, the said girder carrying hydraulic cylinders with chains arranged to sweep it round its pivot, a hydraulic cylinder mou nted on trunnions,with a peel attached to its piston-rod, and a hydraulic cylinder with plunger and roller arranged under the peel, arranged and operating substantially herein, described. I In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 6th day of'October, A. I). 1888.

ARTHUR HARRISON.
